Thirteen counties are currently under a state of emergency: Brantley, Bryan, Bulloch, Camden, Charlton, Chatham, Effingham, Evans, Glynn, Liberty, Long, McIntosh and Wayne. Governor Nathan Deal noted that the hurricane’s path could change at any time and that mandatory evacuation orders may become necessary.

“The safety of Georgians is our first priority, and we urge residents in these areas to remain calm but vigilant as they prepare for potential impact,” Deal said in a press release.

It’s vital, then, that Georgians know their evacuation zone should the situation in the state worsen and should Hurricane Matthew’s path change. The state’s coast is divided into two zones, zone “A” and zone “B.” Consult the following map via the Georgia Hurricane Guide to see which zone you fall into:

You should also familiarize yourself with your evacuation routes, which can be explored in depth on the Georgia Department of Education’s website. Scroll to the very bottom of the page to explore the interactive map.

Meteorologist Brad Nitz noted on Twitter that by Friday night, the center of Hurricane Matthew is expected to be about 100 miles from the shore.
